Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.
Pre-requisites and Co-requisites
UEENEEG001B Solve problems in electromagnetic circuits
UEENEEG002B Solve problems in single and three phase low voltage circuits
UEENEEE004B Solve problems in multiple path d.c. circuits
UEENEEG007B Select and arrange equipment for general electrical installations
UEENEEG025B Plan electrical installations with a LV demand up to 400A per phase
Course Description
This unit covers the design of supply and distribution arrangements, control, protection and selection of equipment for electrical installations with low voltage demand greater than 400 amperes per phase. This encompasses designing schemes for protection of persons and property and correct functioning, compatibility with the supply, and arrangement of circuits, determination of fault levels, effective switchgear, control gear, and protection against over current and over and under voltage and wiring based on calculations to meet required safety and performance standards and functional requirements.

Learning Outcomes
Details of Learning Activities
Classroom tutorial activities are designed consolidate the theory of electrical protections, installation design principles, installation for various electrical devices and metering. Students will participate face to face in learning the regulation and standard for various activities: requirements for electrical wiring, cable selection, switchboard and control panel requirements. It introduces the theory of electrical safety and protections, installation design requirements, metering, various electrical devices, lighting principles and applications. Students will participate in design project for lighting and power installation for specific industry. This practical design project will include the production of various installation drawings, design calculations and selection of various electrical devices for a given specification.
Electrical Installation Project:
 Project activities involve the design electrical installations down to working drawings, of the lighting and power requirements for the installation accordance with the relevant Australian Standards, most notably AS/NZ 1102, AS/NZ 3000 and AS/NZ 3008.1
This project covers the theory and application for the following concepts:
 The fundamental principles of electrical design.
 Design requirements in an electrical installation.
 The principles of producing adequate illumination for various tasks.

Overview of Assessment
This course will be assessed through a range of projects, assignments and progressive tests.
Assessment Tasks
Project 80%
Work simulation project involves power design for an industrial installation. Students will produce installation drawing for lighting, power and switchboard layout drawing according to relevant Australian standards, select appropriate light fittings and lamps. The power installation design will include the calculations relating to the demand & volt drop considerations and fault conditions. Specifications will be provided with work simulation (team or individual basis) or may be negotiated to suit a workplace based application.
Projects may be undertaken as part of a team or individual basis.
Exercises 20%
Work based exercises to be undertaken troughout the unit, in a controlled environment for the specified duration in order to perform tasks autonomously and/or a member of a team .
Assessment activities will be as close as practicable to real work situations and will require “real work” type decision-making by the student involving in class based exercises on :
-General requirements for the supply of electricity.
- Supply and metering requirements.
- Arrangement of switchgear and controlgear.
- Earthing methods and arrangements
- Mandatory and optional testing and verification requirements applicable to special installations.
- Outlines of alternative designs.
- Design exercises within the safety and functional requirements
